On Nov. 16, 2009 at 16:00 h (4:00 pm) a cold front from south hits Buenos Aires with 44 mm (1-3/4 in.) rainfall in only 15 minutes. After a couple of years it was the first time that this happened.

The following satellite imagery (taken from NASA) shows the development from 14:00 h (2:00 pm) to 22:00 h (10 pm).

First some clouds came up and the temperature was around 30 °C (  °F). At 15:30 h (3:00 pm) the first rain drops fall down. At the peak of this event at 16:00 h (4:00 pm) the amazing videos were taken. People were hurrying to find a dry place. The were flooded up to 40 cm (15-1/2 in.) and some trash was swimming in the streets. Only some brave people with their cars were still driving on the streets. Many others were waiting for “better weather”.
